So i had a few diy frag racks and had been using neodymium magnets as they were the only ones i could find that were strong enough. I tried ceramic magnets in many different sizes and they just weren't strong enough. But i found out after another member was buying a frag rack and he saw rust on the neodymium magnets that had been sitting in my tank few months and i had no idea. So i refunded his money and threw the rack in my closet along with the other diy racks. After months i came back across them and decided to try and reef proof them. Let me know if you think they are reef safe now.
I first sanded them

I then painted them with fusion spray paint witch is considered to be reef safe

I then coated both sides with liquid epoxy resin



And heres the finished product


So what do ya think? Would you consider these reef safe now?
